What does the spring rate (150 lbs/in) mean for my vehicle's performance?

A 150 lb/in spring rate means that for every inch the spring is compressed, it exerts 150 pounds of force. This rate offers a firmer ride than stock springs, improving body control during cornering and over bumps, while still providing a comfortable ride for daily driving.

What is the inner diameter of this coilover spring?

This Fox coilover spring has an inner diameter of 2.5 inches. It's important to ensure this matches the specifications of your shock absorber body for proper fitment and function.

What other components are needed to install this spring?

This is a replacement coilover spring. You will need a compatible shock absorber body designed for a 2.5-inch ID spring, along with any necessary spring perch hardware and tools for installation.
